Is R2D2 a practical robotic project?

While I do not mean R2D2 exactly, I do mean his functions, more or less.

R2D2 interfaces will all the various computers and devices, stores and plays
back information, repairs systems, and so on.

While a lot of it is merely science fiction/motion picture device, there is
some utility here I think.

A universal remote control. How many devices do we have that their own
remote control interface. Surely a robot should be able to use voice
interfacing and a library of remote control signatures to control various
appliances.

Vacuum cleaner, well obviously.

Standard computer stuff, word processing via dictation, music, video
playback, etc.

Rocking the babies cradle

and so on.

I think a viable application of a mobile robot is not necessarily something
"robotic" any more than the first viable application of personal computers
was something "computing."

The first personal computers became popular not because of "computing," but
because the could do something mundane like be a better typewriter (word
processor) or better adding machine (spreadsheet).

Maybe robotics is similar, the robot isn't going to get popular because it
does something "new" and "robotic," maybe they get popular because they do
something mundane.
